Abstract
We present a method for joint robust design of linear source and relay filters in a MIMO full-duplex link that supports the transmission of several data streams. The system model accounts for self-interference in the relay, limited dynamic range at the transmit and receive sides of the nodes as well as channel uncertainty. The design criterion is to minimize the worst-case mean square error at the relay input. The resulting non-convex problem is solved by means of an alternating optimization procedure that decouples source and relay filters at each iteration. Optimization of each individual filter is cast as a semidefinite program. Simulations show the impact of channel uncertainty in the mean square error and how the performance of the proposed method compares to a non-robust design.
